Uroflowmetry with Bladder Ultrasound is a functional test of the lower urinary tract specifically designed to assess the quantity of urine excreted from your bladder and the time required to do so which helps understand the emptying phase of the lower urinary tract.

It consists of urinating in a special device which will produce a graphic interpretation of the micturition process.

Once completed, your urologist will perform an ultrasonic evaluation of your bladder to calculate the amount of residual urine inside.

The entire process takes less than 5 minutes.  The examination requires that you arrive at the clinic with a full bladder and does not require any other preparation.

Generally, no preparation is needed.

You may be asked to drink about four glasses of water several hours before the test is performed to ensure that your bladder is full . Also, you should not empty your bladder before arriving for the procedure.

Again, uroflowmetry is best done when you have a full bladder so do not to urinate for 2 hours before the test. Drink extra fluids so you have plenty of urine for the test.
